HTTEIRNEY Patented Nov. 3, 1931 PATENT OFFICE ammo, OI WEEELING, "WEST LOUVBR FOB WINDOWS Application fled Kay 20,

This invention relates to louvers for windows and the like, and the primary ob ect thereof is to rovide means for affording a positive weat erproof louver for such windows. l

A further object of the invention is to provide a weatherproof connection between the louvers and the window frame which assists the louvers in being maintained in either open or closed osition.

A still. urther object of the invention is to provide means for the purpose stated which is of simple construction and which is devoid of arts subject to derangement.

n describing the invention in detail, reference is herein had to the accompanying drawings, in which- Figure 1 is a front elevation of the invention, partly broken away;

Figure 2 is a section on line 2-2, Fig. 1;

Figure 3 is a section on line 3-3, Fig. 1;

Figure 4 is a section on line 4-4, Fig. 1, parts being broken away;

Fi ure 5 is a view similar to Figure 4, but showmg the louvers in open position; and- Figure 6 is an enlarged detail view.-

Referring to said drawings, the reference numeral 1 designates the sides of a window frame or casing and 2 the louvers, said louvers being secured to the holders or end members 3. The members 3, as shown in Fig. 6, have parallel portions 4 that are spaced to receive the ends of the louvers therebetween, the members 4 being secured to opposite sides of a s acer or central member 5 and are secured by rivets 6.

The inner ends of said members 4, which are preferably formed of sheet metal, are provlded with right angular wings 7, said wings being formed with fingers 8 at their inner ends disposed approximately parallel to the members 4. Said members 4 extend throughout the width of the louvers, while the wings 7 and their fingers 8 extend in opposite directions, the fingers 8 projecting beyond the longitudinal centers of the louvers.

Opposed pairs of spring metal strips 9 are secured to the inner faces of the sides of the window frame and are spaced at their confronting inner side edges. The outer sides 1929. Serial No. 864,509.

of the metal strips 9 are secured to the window frame by fastenings 10, while the said inner confronting sides of the strips are free and are capable of being flexed outwardly, as shown in Fig. 6. Said fingers 8 and the wings 7 are engageable with and beneath the said free inner confronting sides of the metal strips 9. When the louvers are in closed position, the wings 7 and theirfingers 8 are completely engaged with and concealed by the plates 9. However, when the louvers occupy completely open position, as shown in Fig. 5, the wings 7 are disposed exteriorly of the strips 9, only the extreme free ends of the fingers 8 projecting in underlying relation to the strips. Each holder 3 is provided with a pinion 11, said pinion meshing with a vertical slidable rack 12. The rack at each end has a slot 13 to receive pins 14, said pins being secured to the window casing. One of the pinions has an operating hand lever 15 connectedthereto which is movable in a slot 16 provided therefor in the window casing.

A central sheet metal strip 17 is secured to the sides of the window frame and is engaged by the wings 7 and their fingers 8, thus roviding a metal-to-metal connection whic is tight and weatherproof. The louvers when made of glass are engaged and cushioned by cushioning strips 8 in the holders 3, as shown in Figs. 3 and 6. I

The wings 7 andthe strips 9 acted to firmly hold the louvers in place and prevent rattling, while the rounded free ends of the fingers 8 function as guides and facilitate the movement of the wings beneath the strips 9.

The louvers have their abutting side edges formed with inclined or angular joints 16, which tightly engage so as to form weatherproof connections therebetween.

What is claimed is- 1. In a louver structure, side supports, metal strips secured to' said supports and havin spaced free inner sides, louver holders pivoted to the supports and composed of side members, spacers between and secured to said side members, the inner sides of the members being extended outwardly to form wings, said wings bein located on opposite sides of the louvers an extending inwardly toward one another, fingers on the inner ends of the wings, a metal strip on the side supports underlying the free sides of the first named metal strips, said wings and fingers being slidably engaged with and beneath the said free inner sides of the strips and with said metal strips, a pinion connected to each louver at one 'end thereof, a slidable rack engaging the pinions to actuate same simultaneously, and means to operate the rack.

2. In a louver structure, side sup orts, metal strips secured to said supports and having spaced free inner sides, louver holders pivoted to the supports and composed of side members, spacers between and secured to said side members, the inner sides of the members being extended outwardl to form wings located on opposite sides 0 the louvers and extending inwardly toward one another, fingers on the inner ends of the wings, said wings and fingers being slidably engaged with and beneath the said free inner sides of the strips, means to actuate the louvers, and a metal strip underlying the free sides of the first named strips and engaging thewings and their fingers.

3. In combination with side supports, metal strips secured to said supports and having spaced free inner sides, louver hold,- ers pivoted to the supports and having wings on opposite sides of the louvers, fingers on the inner ends of the wings, said wings and fingers being slidably engaged with and beneath the said free sides of the strips, and means to operate the louvers.

4. In combination with pivoted louvers and means on opposite sides of the louvers and at the ends thereof and movable therewith, and a stationary means on opposite sides of the pivots of the louvers and engaged over and with said means of the louvers to form weather proof connections therewith.

5. In combination with side supports and louvers pivoted thereto, strips on opposite sides of the pivots of the louvers having free sides adjacent said pivots, and means on the ends of the louvers slidably engaged with and beneath said free sides of the strips to form weatherproof connections therewith. 6. In combination with side supports and louvers pivoted thereto, sides of the pivots of the louvers having free sides adjacent said pivots, and wings on the ends of the louvers slidabl engaged with and beneath said free sides of the strips to form weatherproof connections therewith.

In testimony whereof, I afiix my signature.
